Budaj shouldered the workload for Colorado, making 47 saves. Calgary peppered him with a flurry of shots, many of them from close range.

Calgary (10-8-1) needed the victory to start salvaging what's been a rough November, as the Flames improved to 4-5 this month. Calgary had lost five of their last seven heading into the Tuesday's game, including an embarrassing 6-1 defeat in San Jose last week.

The Avs were without captain Joe Sakic (back) for a fourth straight game and the team hopes he'll be able to play Thursday when Colorado hosts Calgary.

Aucoin took two steps in from the blue-line and lasered the puck over Budaj's glove for the go-ahead goal at 12:28 of the third period.

Calgary's power play was cold Tuesday with zero goals on seven chances until Moss scored with six seconds left and Ryan Smyth in the box for unsportsmanlike conduct.

The Flames opened the third period with a two-man advantage, but couldn't muster a goal. Paul Stastny and Milan Hejduk were slapped with hooking and tripping penalties at the end of the second period.

The Flames outshot the Avs 32-15 after two periods, but the game was deadlocked due to the work of Budaj.

Calgary evened the score at 6:52 of the second period. A sprawling Mike Cammalleri managed to bank the puck across the goal-mouth to Bourque, who scored top shelf with a sharp-angled shot for his fourth of the season.

Colorado posted 1-0 lead at 6:48 of the first period. T.J. Hensick backhanded the puck from behind the goal-line out to an unchecked Svatos, who beat Kiprusoff over his right shoulder for the Slovak's third of the season.

Calgary was scoreless on back-to-back power plays midway through the first period. The Flames had the lion's share of puck possession in the opening 20 minutes and cycled it through the offensive zone, but they couldn't solve Budaj despite a 13-8 edge in shots.
